KoBold Metals Careers: We know that landing on KoBold Metals’ careers page and seeing a short culture statement followed by a handful of external links can leave you wanting more before you commit to an application. This guide fills in the full picture who KoBold Metals actually is, why the company has attracted over a billion dollars from some of the world’s most recognizable tech investors, exactly which roles are open right now, and how to apply through the right regional job board.
About KoBold Metals
KoBold Metals is a Berkeley, California-based company applying artificial intelligence, machine learning, and data science to mineral exploration, with a mission to turn the discovery of critical minerals copper, lithium, nickel, and cobalt — into a repeatable, predictable science rather than a matter of geological luck. The company’s AI-driven approach integrates geoscience with software and hardware engineering to identify mineral deposits that traditional exploration methods have historically missed.
KoBold has drawn some of the tech industry’s most recognizable investors, including Bill Gates and Jeff Bezos through Breakthrough Energy Ventures, alongside Andreessen Horowitz, Mitsubishi, T. Rowe Price, Durable Capital Partners, Equinor, and others. Across multiple funding rounds, the company has raised well over $1 billion, reaching a valuation reported at approximately $4.17 billion in its most recent disclosed round, positioning it among the most well-capitalized private companies in the critical minerals sector.
The Mingomba Project: Why KoBold Is Hiring at This Scale
KoBold’s flagship achievement is the Mingomba copper deposit in Chililabombwe, Zambia, discovered using the company’s AI-driven exploration approach and described as potentially the highest-grade Zambian copper discovery in a century, with ore grades comparable to Ivanhoe Mines’ world-class Kakula deposit in the Democratic Republic of Congo. The company is committing roughly $2–2.5 billion to develop Mingomba into an underground mine projected to produce a minimum of 300,000 tonnes of copper annually from the early 2030s. As of mid-2026, the project has moved from pure exploration into the pre-feasibility and engineering phase, with shaft sinking slated to begin in early 2027 and KoBold reportedly investing $600 million in Zambia by the end of 2026 alone, a scale of private American investment the company’s leadership has described as the largest since Zambian independence. KoBold has already built a roughly 300-person team in-country, the majority of them Zambian, led by in-country CEO Mfikeyi Makayi.
This context matters directly for job seekers: KoBold’s hiring reflects both a fast-scaling AI/data technology company and a genuinely large-scale physical mining development, which is why its open roles span everything from software engineering and data science to underground mine engineering and field drilling operations.
KoBold’s Culture: What the Company Says About How It Works
KoBold organizes its stated culture around three principles, worth understanding before you apply since they shape how the company evaluates candidates and conducts internal work:
- We are Bayesians – the company frames its decision-making, from exploration to business operations, around stating hypotheses, making predictions, running experiments, and updating beliefs based on new evidence.
- We are all owners -a collaborative, multidisciplinary team structure where employees are expected to understand broader context, speak up about concerns, and share work early rather than working in silos.
- We seek the truth – an explicitly stated preference for open dialogue and being willing to be wrong, valuing truth over hierarchy or internal politics.
Candidates who can speak concretely to hypothesis-driven thinking, cross-disciplinary collaboration, and comfort with having their ideas challenged are likely to resonate well with how KoBold describes its own working style.
Where to Find and Apply for KoBold Metals Jobs
This is an important practical detail: KoBold Metals operates three separate regional job boards, all hosted on Greenhouse, rather than a single global listing:
- Global board (job-boards.greenhouse.io/koboldmetals)Â covers remote and in-person roles across most of KoBold’s technology, data science, finance, and corporate functions.
- Zambia board (job-boards.greenhouse.io/zambold) – dedicated to on-site and remote roles specifically tied to the Mingomba project and Zambian operations.
- DRC board (job-boards.greenhouse.io/koboldmetalsdrc) – covers on-site and remote roles connected to KoBold’s Democratic Republic of Congo exploration activity.
If you’re specifically interested in the Mingomba project or field-based mining roles in Zambia, checking the Zambia-specific board directly — rather than only the global listing — is essential, since some roles are posted exclusively there.
Current Open Positions by Department (Global Board)
As of this writing, KoBold’s global job board lists 29 open positions spanning the following departments:
| Department | Example Roles |
|---|---|
| Advanced Technology Group | Director of Mineral Processing, Manufacturing Engineer, Staff Applied Scientist, Staff Client Platform Engineer |
| Data Science | Data Scientist (Global, Australia, UK), Postdoctoral Scholar — AI Researcher for Critical Mineral Discovery |
| Field Operations | Field Operations Lead, HSE Lead (Global Programs and Systems), Senior Drilling Engineer |
| Finance, Accounting & Analytics | Commercial & Scientific Analyst/Lead, Corporate Accounting Lead, International Accounting Manager, International Tax Senior Manager, Senior Manager Finance, Senior Treasury Accountant |
| Geology | Senior Exploration Geologist |
| Human Resources | Executive Assistant, Senior People Systems Analyst |
| Legal and Public Policy | Assistant General Counsel, Employment |
| Mine Engineering | Senior Underground Mine Engineer |
| Operations | Vice President of Business Development, North America, Europe, Africa |
| Software Engineering | Engineering Manager (Data Systems), Frontend Software Engineer, Senior Software Engineer (Decision Science and Scientific Computing), Software Engineer (All Levels, including UK) |
This breadth reflects KoBold’s identity as a genuinely hybrid organization part AI/data technology company, part global mineral exploration and mining operator, rather than a firm hiring narrowly in one discipline.
How to Apply
- Decide which board is right for you: the global board for most remote technology, data science, finance, and corporate roles; the Zambia board for Mingomba-connected and Zambia-based positions; or the DRC board for Congo-based exploration roles.
- Visit the relevant Greenhouse-hosted job board directly.
- Use the search function to filter by department, role, or keyword, the global board alone spans ten distinct departments.
- Open the specific listing and review the role’s location designation carefully (Remote, Remote-US, Remote-UK, Onsite/Hybrid, or a specific country), since KoBold’s postings are quite precise about where a role can be based.
- Apply directly through the Greenhouse application form linked from each posting.
- Consider using the “Create a Job Alert” feature on the global board to be notified directly when new roles matching your interests are posted, given how frequently KoBold’s listings turn over as the company scales.
Tips for a Competitive KoBold Metals Application
- Speak concretely to hypothesis-driven or data-informed decision-making in your application materials, given how central the “Bayesian” framing is to KoBold’s stated culture.
- For technical roles, be specific about relevant domain overlap, KoBold blends geoscience, software engineering, and hardware engineering, so candidates who can articulate how their specific technical background applies to mineral exploration (even from an adjacent field like remote sensing, applied machine learning, or industrial engineering) stand out.
- For Zambia- or DRC-based roles, highlight any prior experience working in-country or in comparable frontier/emerging-market mining environments, given the scale and complexity of the Mingomba project specifically.
- Double-check the exact regional job board before applying, since a role posted only on the Zambia board will not appear on the global board, and vice versa, missing this distinction is an easy way to miss a genuinely relevant opening.
Frequently Asked Questions
- Does KoBold Metals hire remotely? Yes, extensively. Many roles on the global job board are designated Remote, Remote-US, or Remote-UK, alongside a smaller number of onsite/hybrid roles based in the San Francisco Bay Area.
2. Is there a separate job board for Zambia-based roles? Yes. KoBold maintains a dedicated Zambia job board (job-boards.greenhouse.io/zambold) for on-site and remote roles connected to the Mingomba project and broader Zambian operations, separate from the global board.
3. What kind of company is KoBold Metals, a tech company or a mining company? Both, genuinely. KoBold applies AI, machine learning, and data science to mineral exploration and also directly develops mining projects like Mingomba, which is why its hiring spans software engineering, data science, geology, mine engineering, and field operations roles simultaneously.
4. Who are KoBold Metals’ investors? Backers include Bill Gates and Jeff Bezos (through Breakthrough Energy Ventures), Andreessen Horowitz, Mitsubishi, T. Rowe Price, Durable Capital Partners, Equinor, and several other institutional investors, with total funding exceeding $1 billion.
5. What is the Mingomba project? KoBold’s flagship copper deposit discovery in Chililabombwe, Zambia, projected to produce at least 300,000 tonnes of copper annually from the early 2030s, with the company committing roughly $2–2.5 billion to its development.
6. Is there a fee to apply for KoBold Metals jobs? No. All legitimate applications go through KoBold’s official Greenhouse-hosted job boards directly, and no legitimate stage of the hiring process should require payment from candidates.
